Individualiserad matematikundervisning : en kvalitativ studie om lärares arbete med individualisering i förhållande till högpresterande elever

The purspose of this study is to investigate how teachers are working to individualize mathemathics education relative to high-performing students and how they define the therm individualization. According to the Swedish curriculum the teaching process should be based on the students prevoius knowledge and experiences. The teachers should in their preperation take every student in to consideration. To be able to investigate these subjets I prepared following questions:What does the concept of individualization in mathematics mean for the teachers?What does it mean to work with an individualized mathematics teaching?How does teachers individualizes teaching mathematics relative to high performing students?This study is based on a qualitative method with both interviews and observations.

Konsten att uppfattas rätt - Varumärkesstrategier för svenska artister

Personal branding is a common phenomenon within the Swedish business world, although less applied on the competitive and fast paced music industry. In order to strengthen Swedish artists' personal brands and to ensure congruence between the artists' presented identities and the target audiences' perceived images, we have developed a model, containing of seven essential factors. The seven dimensions authenticity, credibility, certainty, openness, availability, awareness and timeliness help improve strength when communicating brand identity, as well as minimizing potential discrepancy between identity and image. This report examines the brand strategies within the Swedish music industry through a case study of Sweden's largest pop star, Eric Saade, where Team Saade's communicated identity is compared to the targets audience's perceived image of Saade. Overall, Saade's personal brand has a high level of congruence, except from the clarity dimension, where his words are considered differing from his actions.

Om matematikundervisningens svåra konst. Ett sätt att undervisa abstrakt bevisföring

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

Biologiska behandlingsmetoder för rening av rejektvatten från biogasproduktion

In this literature review the characteristics of two free-floating macrophytes, water hyacinth   (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.

Six qualitative interviews with such professionals were performed and subsequently analyzed. Since the method of this study is qualitative, no claim of generalizability is made. The interview material has been categorized into themes by means of coding. The result of the study is presented according to those themes.

Elevers perspektiv på bedömning för lärande

The aim of this study was to examine the students' perspectives on formative assessment, partly about how students perceived the assessment in general, partly about what students' opinions were on formative assessment, and partly about students' view of how assessment could be organized to stimulate learning process.  The study consisted of qualitative interviews with six students in grades one in an upper secondary school.The survey showed that students primarily perceived assessment with summative purpose: tests and scores.  Majority of the students experienced that there were too many tests occasions.  Those high-performing students were positive to tests.  However, those lower-performing students felt more negative and became more stressful with the exams.Results showed that they were lack of experience of formative assessment.  All the six students thought that they had not got any chance to involve in the assessments process.  They realized that they had not got adequate feedback about their learning-situations.  With regard to students' wishes about how assessment could be developed in order to improve their learning, it was mainly about more and concrete feedback on tests and assignments.Two models were developed in the final discussion, which showed the author's own perception of formative and summative assessments..

Tätortsklassificering utifrån servicebredd och servicegrad : En klusteranalys av Sveriges tätorter

Statistics Sweden is an administrative agency that delimits built-up areas and produces statistics regarding them. The statistics provide information about the area of the built-up areas, their population number, number of gainfully employees working in the built-up areas, and of buildings. Now Statistics Sweden wishes to extend such statistics by producing a measure regarding how well developed the service is in each built-up area.This study is a contribution to this statistical improvement work and the purpose is to ? by employing geographical information systems and cluster analysis ? classify the Swedish built-up areas according to 1) service width and 2) service degree. A particular built-up area has a high service width if it has many different service functions, such as pharmacies, schools and grocery stores.

Blood compatibility of biomaterials made of recombinant spider silk

Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application. When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation. The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions. Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense. Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials. This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating. Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films. Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

Lycka och livskvalitet ? Vägen till välbefinnande : En studie om den subjektiva upplevelsen av psykiskt välbefinnande

The main purpose of this study was to examine how people who have felt mentally bad, describe their subjective experience of what leads to a mental well-being. The overall research questions were; how does the individual define mental well-being, how does the individual describe the turning-point during her tough period, and in what way does the individual consider that her own effort has influenced her well-being? In order to answer these questions, qualitative research interviews were conducted with persons who?ve felt mentally bad and who?ve got some kind of professional help, and who think that they have a mental well-being today. The empirical material was analyzed from a theoretical resilience perspective. The study?s result showed first of all, that there are different ways to define well-being.

Det konkreta exemplet : En diskussion kring marginaler

The following inquiry begins with one simple question: who is the margin? In other words, what is the referent of the term margin? Is it possible for language to capture connotations of an intended and supposed reality beyond its own limits? My supposition is that margin is a valuable concept to critical studies of the hegemonic order and dominant culture in various contexts. It is therefore necessary to expose the term itself to a critical analysis by attempting to trace its position in different discourses. The intention is to illustrate that the term margin is not merely an abstraction, confined within the framework of intricate theoretical rhetoric.In a deconstructive analysis of Gender Trouble by Judith Butler and Can the Subaltern Speak? by Gayatri Chakravorty Spivak, based on the work of Jacques Derrida, I study the significance of the term margin and explore how the use or non-use of concrete examples affects the reception of both the term margin and ultimately the text as a whole.The study of these two texts reveals that some of the very same critique raised by Butler and Spivak is itself applicable to the authors? own theory production.
